Honorable Mention: Cro Cop's Left High Kick

Likely the most famous single strike in the history of the sport. Cro Cop famously utters about his kicks "right leg hospital, left leg morgue" and nobody could argue with the string of limb bodies left in rings by his left kick.

An absolute force in the 2000s, this strike is now an honorable mention because for all intents and purposes, the strike has been retired for about four years now. But it was stunning to watch in its day.

10. Chris Leben's Footstomps

Perhaps the most mean spirited strike on this list, any time this gritty middleweight finds himself in a clinch rather than rest, Chris Leben prefers to punish his opponent's foot with heel stomps. The purpose of these strikes is to injure the foot by breaking the little bones and nothing else.

Leben's nickname, "The Crippler," is rather fitting considering his vicious use of these stomps.

9. Rampage Jackson's Right Hook

When Quinton "Rampage" Jackson was in Pride he was best known for his slams, but he has worked diligently on improving his boxing. He now boasts one of the best inside boxing games, with an array of tight hooks and upper cuts.

His most famous punch was the right hook that began the dramatic decline of the great UFC Champion Chuck Liddell.

8. Dennis Siver's Spinning Back Kick

A German kickboxing champion, Dennis Siver has always had a dramatic flair to his striking game. Siver's strongest strike is actually his right hand, which packs quite a punch and, as a result, he's been the focus of many opponent's game plan.

So Siver likes to use his right hand early in fights and force opponent's to circle away from it, right into a killer spinning back to the liver.

7. Edson Barboza Jr.'s Leg Kicks

There are many great leg kickers in MMA, but Edson Barboza's brutal leg kicks have turned many heads, even more than his spinning hook-kick turned Njokuani's head. They are quick, accurate and just devastating.

There are perhaps no better examples of the damage that can be caused by leg kicks than the way Barboza left Marcelo Guidici and Mike Lullo crumpled on the canvas for Leg Kick TKO wins.

4. Wanderlei Silva's Knee Strikes

There is something very primal and visceral about the Muay Thai clinch, and Silva seems to love everything about it. And MMA fans were mesmerized by his ability to render opponent's helpless as he peppered them with knees, leaving them broken on the mat.
